Title: Improvements in process for obtaining a mixture of alumina and an insoluble calcium salt and for obtaining alumina
IPC: C01F7/18
Filed: 1933-07-31
Abstract: Calcium aluminate is extracted with water, and alumina and an insoluble calcium salt are precipitated from the solution by a reagent such as carbon dioxide, phosphoric acid or fluoric acid. When carbon dioxide is used, calcium carbonate may be removed from the mixed precipitate either by dissolution in say dilute hydrochloric acid preferably after calcination at 500--600 DEG  C., or by calcining the precipitate to convert the calcium carbonate to lime which is washed out by water, or by dissolution in water containing carbon dioxide.  The bicarbonate solution obtained is subjected to heat or vacuum to remove carbon dioxide, or treated with lime.  The process is preferably effected in a cyclic manner, the leaching water being continuously circulated.  A leaching temperature of 25--35 DEG C. is specified.  The aluminate solution obtained contains 0,2--3 grms. alumina per litre.  The calcium aluminate may be produced from siliceous bauxite.  Aluminate cements and clinkers may be leached. The calcium carbonate-alumina precipitate may be used for the manufacture of lacs, abrasive products or aluminium sulphate, or may be mixed with baryta for the production of barium aluminate.  This product may be used in the purification of water.ALSO:Baryta is added to a precipitated admixture of calcium carbonate and alumina to form barium aluminate.  This product is adapted for use in the purification of water.

Title: Method of and means for automatically controlling the controlling the output of a carding engine involving the condenser system
Inventor: LIVERSIDGE CHARLES
IPC: G01N33/34
Filed: 1951-09-14
Abstract: 734,078. Carding-engines; testing and measuring slivers &c. WOOL INDUSTRIES RESEARCH ASSOCIATION and LIVERSIDGE, C. Sept. 15, 1952 (Sept. 14, 1951], No. 21598/51. Classes 120(1) and 120(3). [Also in Group XXXV] In a method of automatically controlling the production of slubbings or their equivalent by a carding engine under a condenser system, variations in the weight per unit area of the web at a point within the machine are measured and/or recorded by a device, which may include the mechanism described in Specification 727,403, [Group XXXVIII], (see Group XXXV),  the output of which regulates the speed of the doffer relative to that of the swift or its equivalent so as to maintain the weight per unit area of the web at a desired value. The device may project through or on the web some form of non- varying radiation e.g. a beam of light, ultrasonic energy, Beta rays or sound waves, to assess variations in web thickness and hence weight per unit area, or it may be a mechanical feeler gauging the thickness directly. As shown a running web 2 passes between one or groups of photo-electric cells 4 and 7 so placed that the latter receives light from the same area of the source 1 as cell(s) 4 receives it after it passes through the web 2 : variations in the web cause changes in the light falling on cell(s) 4 and hence the current therethrough : the currents in the cells 4 and 7, amplified in amplifier 9 if required, are compared differentially and a resultant signal proportional to a deviation in the web from a desired value fed to a recorder 10 and also to a regulator 11 in a variable ratio transmission unit 12 which interrupts the normal mechanical linkage 15-17 through which by belt transmission the swift 16 drives the doffer 5 and condenser 6 via wheel 14, or the linkage 15 may be replaced by a separate local power unit such as an electric motor still driving the unit 12, to effect the required correction : the setting of the unit 12 is transmitted by a " closed-loop " servo system 13 comprising a self-synchronous transmitter and motor or to a torque balance device as described in Specification 589,423, [Group XXXVIII], where it is compared with the output or time or amplitude function thereof ; any error due to change in the weight per unit area of the web exceeding predetermined limits causes a relay-operated electric motor to cancel the error. In modifications (not illustrated) the error signal, instead of being fed to recorder 10, is made to adjust the amount of light falling on cell(s) 7 in such manner that the signal tends to reduce to zero and the displacement of the light adjusting device is recorded and provides the measure of the necessary adjustment of doffer speed : also the cell(s) 7, by arrangement of mirrors and switching devices, may replace cell(s) 4 as well as effecting reference and balancing functions.

Filed: 1961-06-15
Abstract: 931,471. Automatic control of viscosity. INSTITUT FUR GRAFISCHE TECHNIK. June 15, 1961, No. 21693/61. Class 38 (4). [Also in Group XIX] In a control system for regulating the viscosity of a fluid, a piston is allowed to fall freely through the liquid, the time of fall being measured by photo-cells and being compared electronically with a set falling time characteristic of a desired viscosity to obtain a difference signal which is used to control the opening of a supply cock for a flow of solvent into the fluid whereby the viscosity is maintained constant at the desired value. As shown, a measuring insert 1 (see Group XIX) has a hollow cylinder 2 projecting into a liquid 3 the viscosity of which it is desired to regulate. A piston within the cylinder 2, movable by an electromagnet 6, is allowed to fall freely through the liquid. The time of fall is measured by photo-cells (not shown in Fig. 2) and is compared in a control component 12 with a set falling time representative of a desired viscosity selected by a pointer 16. Any difference between the actual and set times causes a signal to be produced whereby a supply cock 19 is opened for the flow of solvent C to the liquid 3 the viscosity of which is thus maintained constant.
